Answer:
Complete C++ code along with output and comments for explanation is provided below.
C++ Code with Explanation:
#include <iostream>
using namespace std;
// implement a function named print_sum which takes three input numbers of type int and returns the sum of these three numbers.
int print_sum(int num1, int num2, int num3)
{
// initialize the variable to hold the value of sum
int sum;
// add the three numbers and store the result in the variable sum
sum = num1 + num2 + num3;
// print the sum of three numbers
cout<<"The sum of three numbers is: "<<sum<<endl;
}
// driver code starts here
int main()
{
// initialize the three input numbers
int x,y,z;
// get the three numbers from the user
cout << "Please enter number 1: "<<endl;
cin >> x;
cout << "Please enter number 2: "<<endl;
cin >> y;
cout << "Please enter number 3: "<<endl;
cin >> z;
// call the function print_sum to calculate the sum
print_sum(x,y,z);
return 0;
}
Output:
Please enter number 1:
24
Please enter number 2:
13
Please enter number 3:
